How this count works
Fall starts at the September equinox. The US Naval Observatory publishes its time to the minute, and this page converts that time to your time zone, so the date can differ from place to place.
This is the astronomical fall of the Northern Hemisphere. Meteorological fall starts on September 1. In the Southern Hemisphere the seasons are reversed.
For example
The September equinox of 2026 is at 00:05 UTC. In New York that is September 22, 2026 at 8:05 PM, which is the date this page counts to there.
Questions about this countdown
Why can the date differ between time zones?
An equinox or solstice happens at one instant for the whole world. Depending on your time zone, that instant can fall on a different calendar date.
Are these the meteorological seasons?
No. These are the astronomical seasons, which start at the equinoxes and solstices. Meteorological seasons use whole months: spring is March, April and May in the Northern Hemisphere.
Does the count include today?
No. The day count leaves out today and includes the date the season starts in your time zone.
